Does anyone here remember how long it took Canon to address issues with the 5D Mark II? It definitely wasn't this quick!

Does anyone remember issues with the 5DII ? Talk about clutching at straws.

I received on of the first 5D MK II's about November 27, and a week or so later, on December 8, reports of a issue from black spots appearing on bright highlights when people shot Christmas lights. NR normally made them go away, so many did not see them. I had to review my shots to find one that had them.

On December 15, about two weeks after the first Camera deliveries, Canon announced that they were looking at the issue. Canon modified the firmware to eliminate them. On January 9, three weeks later, Canon issues a firmware update to fix them.

So, it took ~ a whole month from initial reports to verify the issue, develop a firmware update, test it and release it.

How many D810 users will have their camera fixed in a month?

I also got my 5DII when it was first released and have never had an issue. Neither have I ever updated the firmware - 'cos I never do

The 5DII must be remembered as one of the best sorted cameras right from its inception; not a good example to use !

Curious that the camera must be sent to a service center for the fix to be applied.

Kind of like how if you have a 1DC and just want a regular firmware upgrade.

Except that it's adding features to the 1D C vs. fixing a defect for the D810. Oh, and one is a >$10K camera intended for cinema professionals, and the other is a "versatile camera for versatile shooters."

Whilst it may not have impacted you, I know people for whom it did delay their purchasing decision until after it was fixed/resolved.

yup, I remember seeing those xmas light black dot examples and I waited until after a FW update before getting one - but no matter what firmware version I ran on mine, it was a bandy bass terd of a camera.

Seriously?? How can you possibly conclude the 5DII can deliver good images if you are showing shots that were clearly taken without the lens cap properly covering the lens. As everyone Aglet knows, the only way to properly evaluate IQ is to shoot a black frame with the lens cap in place, then push the exposure several stops. How dare you show actual pictures of real scenes shot with the 5DII in some sort of misguided attempt to distract everyone from the proper way to evaluate IQ. What abominable hubris!

Weird. You must have had a dud. Couldn't possibly have been user error.

I'm sure I did get a dud. Teach me to buy a first run of a new product! (Ooops, i did that again w d800s and XT1, no issues tho except the fuji's light leak)

The 5d2 banding flaw I first noticed in gray midtones and clear blue sky, then discovered I was not the only one complaining about it.There were 2 sources of vertical banding. One was a FPN read noise with an 8 pixel cycle, like the 7D/60D/etc.

The other was a different issue, and actually the first flaw I'd noticed in the 5D2's smooth midtones. After looking more closely I found the other noise issues. Then I was just seriously annoyed!

But, back to the other banding issue. I've also just discovered it in one of my recently acquired 2nd-hand Fuji XE1s.About the central third of the sensor is affected. When doing a dust-check at 200mm and f/22, I found this central region was also inhabited by wide bands of slightly lighter-darker areas, but not perfectly regular in alignment. When I shot another test w-o any lens, I could no longer see this issue. So it is some strange sort of interference effect?.. Anyone have a good guess?.. I thot it if was a simple interference it might make radial patterns but it created wider, relatively vertical bands.When I still had the 5d2 I didn't try a no-lens shot to see if that effect was still there.If I get some time, I'll post an example from the Fuji, it's very similar.

I suspect it might be minor misalignment of micro-lenses over their pixels producing subtle variations in effective QE.

I'm on the fence with this one. Dust with the D600 100% should have been caught in evaluation period before launch. But finding an issue that only shows up in crop mode + long exposures might be more of the weird lightning bolt of an issue you don't find until you release it to the masses.

The point is that they denied issues with the D600, and recently agreed to replace all D600's in China with D610's. We'll be seeing those D600's on ebay soon.

Hopefully, they have learned to react when a issue is spotted rather than go into denial. That costs them much more than the eventual fix and loss of reputation.

This is one of the reasons I'm not fond of the idea of adding Nikon to my kit.

Does anyone know if Sony has had any such problems, and if so, how their customer support of the issue/turnaround time on a fix is?

I'll be renting one this fall to evaluate it with some ultra high DR fall foliage situations and will be sure to apply the firmware update, then report if I'm seeing dots on some long exposures I have planned.

I'm still trying to find a sunset where some some subject in the scene hits the noise floor of the D810 at ISO 64. I just can't. I need one of those special spectacular sunsets that happen like once a year where the clouds light up half an hour after sunset.

I had similar trouble with a Pentax 645z at ISO 100. These sensors are incredible.

Remember: shadow SNR is still limited by shot/photon noise. Only extending FWC or sensor size will help here.
